Abstract
A back-plunger type displacement detecting apparatus is provided having a thinner case. The back-plunger type displacement detecting apparatus has a spindle secured to the case to extend perpendicular to the display surface of a digital display unit. A movable member is secured to the case and extends perpendicular to the direction of movement of the spindle. A converting mechanism converts the displacement of the spindle into displacement of the movable member. An electrical unit detects the displacement of the movable member and displays the detected value on the digital display unit.
Claims16
A displacement detecting apparatus having a digital display unit on a case, the apparatus comprising:
- a spindle secured to the case, said spindle moving perpendicular to the display surface of said digital display unit;
- a movable member secured to said case to move perpendicular to an axial direction of said spindle;
- a converting mechanism disposes between said spindle and said movable member to convert axial displacement of said spindle into displacement of said movable member;
- a detecting device that detects the displacement of said movable member and digitally displays the detected value on said digital display unit, wherein said converting mechanism comprises first and second contact members, the first contact member being fixed to one of said spindle and said movable member at an angle of about 45 degrees relative to said movable member, said second contact member being fixed to the other one of said spindle and said movable member, said second contact member being in contact with said first contact member;
- and
- an angle adjusting device to adjust the angle of said first contact member relative to said movable member.
A displacement detecting apparatus comprising:
- a case having a digital display unit formed on a surface of the case;
- a spindle extending from said case to move in an axial direction that is substantially perpendicular to said surface having the digital display unit;
- a movable member that moves substantially perpendicular to the axial direction of the spindle;
- converting means for converting axial movement of said spindle into movement of said movable member;
- detecting and controlling means for detecting the movement of said movable member and for controlling the digital display unit based on the detected movement, wherein said converting means comprises first and a second contact member, the first contact member being fixed to one of said spindle and said movable member, said second contact member being fixed to the other one of said spindle and said movable member and being in contact with said first contact member;
- and
- an angle adjusting device to adjust the angle of said first contact member relative to said movable member.
